TMA Bolaget AB, a leading Swedish road safety enterprise, has recently added two fully electric Mercedes-Benz eEconic special-purpose vehicles to its fleet.
The special-purpose vehicles are so-called TMA-vehicles, which are equipped with mobile impact absorbers – also known as TMA or truck-mounted attenuator – to secure construction sites of short duration, for example. The truck-mounted attenuator can protect all parties involved in the event of a collision.
The two eEconic were equipped by Vicky Teknik, which has many years of experience with TMA bodies. The vehicles are equipped with a separate battery system with approx. 20 hours of operating capacity per charge, and additional solar cells.
The eEconic is based on the tried-and-true Econic and was specifically developed as an all-electric alternative for locally CO2-neutral use in urban environments. Primarily used for waste management up until now, it will now be part of TMA operations in Sweden.
The technological heart of the eEconic is the drive unit — an electric axle with two integrated electric motors and a two-speed transmission. The eEconic is fitted with three battery packs, for a total installed capacity of 336kWh. The batteries can be recharged from 20 to 80% in 75 minutes, using a 400A 160kW charger.
Both liquid-cooled motors generate a continuous output of 330 kW as well as a top performance of 400 kW. In addition, when driving with foresight, electrical energy can be recovered through recuperation — a major advantage, especially in the stop-and-go operation of refuse collection.
